Petunia plant named ‘Whip Pur’

ABSTRACT

A new and distinct cultivar of  Petunia  plant named ‘Whip Pur’, characterized by its low trailing, outwardly spreading and mounded plant habit; freely branching habit; freely flowering habit; single flowers that are red purple in color; and good garden performance.

Botanical classification/cultivar designation: Petunia×hybrida cultivar Whip Pur.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Petunia plant, botanically known as Petunia×hybrida, and hereinafter referred to by the cultivar name Whip Pur.

The new Petunia is a product of a planned breeding program conducted by the Inventor in Gilroy, Calif. The objective of the breeding program is to create new freely flowering Petunias with trailing and spreading plant habit and attractive leaf and flower coloration.

The new Petunia originated from a cross-pollination made by the Inventor in September, 2000 of a proprietary selection of Petunia×hybrida identified as code number 00-382-4, not patented, as the female, or seed parent, with a proprietary selection of Petunia×hybrida identified as code number 00-381-2, not patented, as the male, or pollen parent. The new Petunia was selected as a single plant from the resulting progeny of the cross-pollination in a controlled environment in Gilroy, Calif. in March, 2001.

Asexual reproduction of the new cultivar by terminal vegetative cuttings since March, 2001, in Gilroy, Calif. has shown that the unique features of this new Petunia are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Whip Pur have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity and daylength without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Whip Pur’. These characteristics in combination distinguish ‘Whip Pur’ as a new and distinct cultivar:

-   -   1. Low trailing, outwardly spreading and mounded plant habit.     -   2. Freely branching habit.     -   3. Freely flowering habit.     -   4. Single flowers that are red purple in color.     -   5. Good garden performance.

In side-by-side comparisons conducted in Gilroy, Calif., plants of the new Petunia differed from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Petunia were more freely flowering than         plants of the female parent selection.     -   2. Plants of the new Petunia had smaller flowers than plants of         the female parent selection.

In side-by-side comparisons conducted in Gilroy, Calif., plants of the new Petunia differed from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Petunia were more outwardly spreading than         plants of the male parent selection.     -   2. Plants of the new Petunia had smaller flowers than plants of         the male parent selection.     -   3. Plants of the new Petunia and the male parent selection         differed in flower color as plants of the male parent selection         had scarlet-colored flowers.

Plants of the new Petunia differ from plants of the Petunia cultivar Whip Rosein, disclosed in U.S. Plant patent application Ser. No. 10/818,347, primarily in flower color.

Plants of the new Petunia can be compared to plants of the cultivar Supertunia Mini Blue, not patented. In side-by-side comparisons conducted in Gilroy, Calif., plants of the new Petunia differed from plants of the cultivar Supertunia Mini Blue in the following characteristics:

-   -   1. Leaves of plants of the new Petunia were more rounded and         darker in color than leaves of plants of the cultivar Supertunia         Mini Blue.     -   2. Plants of the new Petunia and the cultivar Supertunia Mini         Blue differed in flower color as plants of the cultivar         Supertunia Mini Blue had blue purple-colored flowers.

DETAILED BOTANICAL DESCRIPTION

Plants of the cultivar Whip Pur have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype. The aforementioned photographs and following observations and measurements describe plants grown in Gilroy, Calif., under commercial practice in a polyethylene-covered greenhouse during the summer with day temperatures ranging from 24 to 29° C., night temperatures ranging from 13 to 18° C. and light levels about 2,000 foot-candles. Plants used for the photographs and description were about 12 weeks from planting rooted cuttings. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
